Listen, it’s not about rushing or whatever but the only way the game is gonna be in a good state long term is with AQ out and alterac valley. Phase 3 anyone leveling is just going to get camped till they quit the game, faction imbalances are going to get worse, it will be a disaster. AQ gives the game some depth and gives more raid content besides 2-3 hours of the same things every week.
Before you rage consider that a phase for naxx is fine, but we really need phase 4 immediately to make the game good.
